Cerebras alternatives
Cerebras is about speed, on a deliberately short model list. The alternatives below are the other fast and per-token hosts, and MagmaRouter for an uncensored build of the same Qwen3.8 27B that Cerebras serves aligned.
What Cerebras is, and where it stops
Cerebras runs inference on its own wafer-scale hardware and is very fast: its docs list two shared models, gpt-oss-120b at about 3,000 tokens a second and qwen-3.8-27b at about 1,850, with a 128K to 131K context on paid tiers and less on free (checked 2 October 2026). Both are the original aligned releases, and anything else means its dedicated inference offering.
Other options people compare with Cerebras
| Option | What it is |
|---|---|
| Groq | Very fast inference on its own LPU hardware, over a short list of models compiled for it. |
| Fireworks AI | Fast serverless inference for mainstream open models, plus dedicated deployments and fine-tuning. |
| Together AI | Large catalogue of mainstream open-weight models, per token on serverless or on dedicated endpoints, plus fine-tuning. |
| Baseten | Per-token Model APIs over a short list of mainstream open models, and dedicated deployments billed by the minute. |
| DeepInfra | One of the cheaper per-token hosts for open-weight models, with a wide catalogue that changes as models are added and retired. |
| OpenRouter | A router over many providers: one key and one bill for hundreds of models, each served under its provider's policy. |
What MagmaRouter carries instead
MagmaRouter sells 6 uncensored models on one OpenAI-compatible endpoint, every one able to call tools. Ordered for this particular job rather than by a single ranking: GLM 5.3 Flash Xploded leads because it is the cheapest of the set on output at $1.00 per million tokens.
| Model | Context | In | Out | Tools |
|---|---|---|---|---|
| GLM 5.3 Flash Xploded glm-5.3-flash-xploded |
1.05M | $0.30 | $1.00 | Yes |
| DeepSeek V4.1 Flash Xploded deepseek-v4.1-flash-xploded |
1.05M | $0.30 | $1.50 | Yes |
| MiMo V2.6 Flash Xploded mimo-v2.6-flash-xploded |

Switching takes one base URL
Anything that speaks the OpenAI chat completions format works unchanged. Point it here, use a MagmaRouter key, and name the model from the table.
curl https://api.magmarouter.com/v1/chat/completions \ -H "Authorization: Bearer sk-mr-..." \ -H "Content-Type: application/json" \ -d '{ "model": "glm-5.3-flash-xploded", "messages": [{"role": "user", "content": "Hello"}] }'
FAQ
Is MagmaRouter actually uncensored, or does it just say so?
MagmaRouter does not moderate requests. It prices the call, holds the money against your key cap and passes the request to the model. What comes back is whatever that model does: an uncensored build refuses far less than a frontier model but can still decline, and only an abliterated build has the refusal direction removed outright. Neither tag is a promise that any given answer will arrive.
What does it cost compared with Cerebras?
You pay per token at the rates in the table above, with no subscription. $0.30 in and $1.00 out per million tokens for GLM 5.3 Flash Xploded.
Can I cap what a key is allowed to spend?
Yes, and the cap is enforced before the request goes upstream rather than reconciled afterwards. The reply cannot physically cost more than the hold placed before it was sent.
Will it work with my existing client?
If the client takes an OpenAI-compatible base URL, yes: point it at https://api.magmarouter.com/v1 with a MagmaRouter key. Claude Code and the Anthropic SDKs use the Anthropic format, which is served too.
